Strange problem. I am developing an application using 2 JFrames. Both JFrames are loaded during start up but only JFrame1 is visible. Pressing a button on JFrame1 sets JFrame1 invisible and JFrame2 visible. What happens is JFrame1 doesn't disappear and JFrame2 appears on top of JFrame1. The strange thing is this only happens once and this bug clears after switching back and forth from JFrame1 and JFrame2. Have you seen or heard of anything like this before? I've tried waiting before pressing the JButton but this doesn't help.
